Hi All,
*Sorry, due to a copy and paste error I sent week 43's summary again. Please see below week 44.*
Please find below a brief summary of the progress Collabora have made last week on Weston/Wayland.
Weston / Wayland
- Going over SPEC-3663, SPEC-3653 and SPEC-3665 to determine
which ones are suitable for receiver/transmitter improvements.
SPEC-3663 (seat not available depending on the order) shows the
duality of the receiver and the transmitter, that acts both as a
server and a client in the same time. For instance the receiver
contains the server implementation for the Waltham side, but acts
as client for the local compositor, so the receiver can be started
before the transmitter, but it won't be able to react (install
proper seat handler) if the transmitter connects after that. Some
further changes to how the client interacts with both are required
to let the user know before starting the receiver that the
transmitter is on-line at that time. So far, we just print out
that we won't have a valid seat if the receiver is started after
the transmistter.
- From SPEC-3664 (transmitter surface is disconnected, what should
the receiver display?) dicovered SPEC-3675 (Extend receiver to
allow dispatching events for main surface and still receive events
from the transmitter). With the addition of remote surface removal
I've noticed that receiver wasn't handling/calling the destroy
handlers, and in the same time, reviewers showed the fact that
receiver will block wait for compositor events. I've started
working on having a work-around such that the receiver is able to
both dispatch transmitter events and also handle (local)
compositor events. Previous changes to receiver resorted to using
a thread to handle the gstreamer pipeline and avoid using
dispatching wayland blocking functions.
- Added comments to SPEC-3673 (AGL virtual Keyboard)
- Added a fix for SPEC-3630 (Incorrect order of surfaces
destruction if XDG_RUNTIME_DIR is not set) and SPEC-3672
(agl-compositor produces segfault when exiting).
- Reviewed, added comments, investigation and discussions about
https://gerrit.automotivelinux.org/gerrit/c/src/agl-compositor/+/25486
(desktop: Delay surface creation until committed) submitted by
Walter.
Kind regards,
Nick
